This is getting ridiculous. Channel 7 here in Australia just ran the video of the flypast on their network news this evening. They appeared to have the actual video (though they ran it in slow motion) rather than the assembly of stills that was posted in here.
Rather than join the chorus of speculation, personally I'd love to learn the details of what permissions he did and did not have. I find it hard to believe that an experienced captain would decide to imitate Tom Cruise unless he thought his actions were authorised. The presence of the CEO (and the friendly atmosphere during the post-flight champagne) would certainly indicate that nobody realised at the time that rules were being broken.
As usual, I wonder if we'll ever have the full facts.
